ColorHarmony is a Processing.org library developed by Rolf van Gelder, CAGE Web Design.

With this library, you can generate so-called harmonized color palettes (also called color schemes), which means a set of colors that ‘look good together’.
The generated palettes can be used, real-time, in Processing sketches.

There are four types of palettes available: monochromatic, analogous, complementary and triads.

Example of ColorHarmony palettes (see the palettes.pde example)

Every palette is based on a base color. Starting from the base color, the other colors are generated, using color theory formulas.

“Another important parameter of a color scheme is the base color. This means, a base hue the model uses to specify all other related colors in the palette. Color schemes built on the very same model, based on deep red, bright orange, or steel blue color will look very different and express different emotions. Besides the base color hue and the choice whether the base is a warm color or a cold color, also its saturation and brightness are important, influencing the final look of the created color scheme.”
(quote from Colorpedia)

In the library, there is also an option to use a random base color for generating the palettes.

Another option is to generate a fully random harmonized palette: the palette type and base color will be selected at random.

The library contains a set of color conversion methods, which you, of course, also can use without generating the palettes.

Check out the Javadocs for all the details and examples.

Compatibility

The library has been compiled with Java jdk1.6.0_45 and uses the Processing core v2.2.1 jars.
Therefore it’s compatible with Processing v2.2.1 up to v3.3+.
